Commonly, 20% of the cement (by weight) in a concrete mix is replaced by fly ash. Fly ash enhances the workability, durability, and ultimate strength of concrete at a lower cost than cement. However, mercury sorbents can change the ash properties to make it unsuitable as a concrete additive. New “concrete-friendly” sorbents can keep the revenues from ash sales flowing.

Measuring combustion airflow in a coal-fired power plant can be problematic when using annubar instruments that feature small holes that can easily plug with coal dust. Sierra Instruments eliminates this big maintenance headache with its more-accurate, nonplugging thermal mass flow meter design.

Industry experts say raw uranium will face increased demand, reduced supply, and higher prices. Will the market bear out those predictions?

Could demand from plug-in hybrid cars crash the grid? A DOE national lab addresses the issue.

Working for Uncle Sam can be worthwhile or a life-sapping grind, depending on which agency employs you, according to a new survey by the U.S. Office of Personnel Management. Guess which agency ranked best. (Hint: It’s related to power.)

What role will coal play as the nation moves toward trying to reduce greenhouse gases? The picture is mixed, as these news stories from around the country demonstrate.

Climate change legislation, despite its environmental focus, will raise vast sums of money. The Washington turf wars over how to spend the money will dwarf the skirmishes we’ve seen so far.

Did a recent Supreme Court decision give a license to firms to use “best practices” concepts to gut effective environmental standards?

The U.S. Nuclear Regulatory Commission (NRC) in early April granted Entergy Nuclear an extended license for the Oyster Creek nuclear plant in New Jersey, the oldest operating nuke in the U.S. The plant will now be able to operate until 2029, unless the NRC at some point in the future grants a further license extension. Nuclear power advocate William Tucker, with tongue in cheek, advocated closing the plant and other elderly units in the Northeast, in a commentary in the National Review. Tucker’s comments are reprinted with permission.

Does customer satisfaction play a meaningful role in guiding utility operations? Many utilities think it does, as do many regulators. The market apparently doesn’t. Data suggest that the jury is out on the question, and the intuitive answer may not match the empirical evidence.
